Thanks a lot!
> Malformed URL exception while deploying Samza on a pure IPv6 VM
> ---------------------------------------------------------------
>
> Key: SAMZA-2681
> URL: https://issues.apache.org/jira/browse/SAMZA-2681
> Project: Samza
> Issue Type: Bug
> Environment: Pure IPv6 deployment
> Reporter: Vishal Ranjan
> Assignee: Vishal Ranjan
> Priority: Critical
>
> In our product we are expanding our support for IPv6 environment.
> We earlier tested deploying Samza in a dual stack environment, and it worked
> fine.
> Recently we got our hands on a pure IPv6 lab, and while testing we came
> across an issue when starting Samza.
>
> Looking at the stack trace it seems like the url is not formed correctly for
> IPv6 deployment. The IPv6 address should have been decorated inside '[ ]’,
> but that isn’t the case.
> Here is the stack trace. The ip of the VM where Samza is deployed is
> 'fc00:192:168:22::14’.
